Description

Technical Field

[0001] This utility model relates to the field of circuit board recycling technology, and more specifically to a metal material purification and refining device for circuit board recycling. Background Technology

[0002] The metal purification and refining equipment for circuit board recycling is a professional device designed specifically for recycling metals such as copper, gold, silver, and palladium from waste circuit boards. It separates and purifies metals from circuit board substrates and impurities through a combination of physical and chemical processes, realizing the recycling of metal resources. Taking the smelting furnace as an example, it can melt the crushed and sorted metal particles at high temperature, causing non-metallic impurities such as resin and plastic to burn or form slag. The molten metal becomes crude metal ingots after being cooled by slag removal.

[0003] The furnace lid on top of a traditional smelting furnace can block heat dissipation during high-temperature smelting, reduce heat loss, and maintain the high temperature inside the furnace to help melt metal particles. However, in the existing technology, the furnace lid and the furnace body are mostly connected by clamps, bolts, or snap fasteners: bolt connections need to be tightened one by one, clamp connections need to be adjusted repeatedly, and snap fastener connections need to be fastened one by one. Especially when the furnace lid is large, it is difficult for a single person to operate and often requires the cooperation of multiple people. A single disassembly and assembly takes tens of minutes or even longer. In the circuit board recycling process, the smelting furnace needs to be frequently fed, slag removed, or repaired. Therefore, the traditional connection method is prone to interruption of the production process due to the excessive time spent on disassembly and assembly. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a metal material purification and refining device for circuit board recycling, so as to solve the problems existing in the background art.

[0005] The utility model provides the following technical solution: a metal material purification and refining device for circuit board recycling, comprising a smelting furnace body and a furnace cover disposed on the top of the smelting furnace body, a positioning ring fixedly connected to the top of the smelting furnace body, a retaining ring provided at the bottom of the furnace cover, a sealing rope embedded inside the retaining ring, positioning components installed at equal intervals inside the furnace cover, a sealing cylinder fixedly connected inside the furnace cover, a sealing cavity provided inside the sealing cylinder, a sealing disc longitudinally and slidably connected inside the sealing cavity, a turntable rotatably connected inside the sealing disc, a threaded column fixedly connected to the top of the turntable, a connecting pipe fixedly connected inside the furnace cover, and the bottom end of the sealing cavity connected to the input end of the positioning components through the connecting pipe.

[0006] Furthermore, the positioning component includes rotating grooves equidistantly formed inside the furnace cover. A rotating block is rotatably connected to the inside of the rotating groove via a pin. A rotating plate is fixedly connected to the surface of the rotating block. A positioning block is fixedly connected to the surface of the rotating plate. The inside of the rotating groove is connected to the inside of the retaining ring. A connecting plate is rotatably connected to the surface of the rotating plate. A slider is laterally slidably connected inside the furnace cover. The end of the connecting plate away from the rotating plate is rotatably connected to the surface of the slider. A fixing rod is fixedly connected to the center of the surface of the slider. A sealing plate is fixedly connected to the end face of the fixing rod. A sealing groove is formed inside the furnace cover. The outer surface of the sealing plate is slidably connected to the inside of the sealing groove. The inside of the sealing groove is connected to the bottom of the sealing cavity via a connecting pipe.

[0007] Furthermore, a handle is fixedly connected to the top of the threaded column, and vent holes are equidistantly opened on the top of the sealing cylinder. The inner top of the sealing cavity is connected to the outside of the sealing cylinder through the vent holes.

[0008] Furthermore, the outer surface of the threaded column is threadedly connected to the inside of the sealing cylinder, and a sealing ring is fixedly installed on the outer surface of the sealing disc.

[0009] Furthermore, the size of the positioning ring matches the size of the retaining ring, a sealing ring is fixedly installed on the outer surface of the sealing plate, and the rotating plate is rotatably connected to the inside of the rotating groove through a rotating block.

[0010] Furthermore, the surface of the positioning block is arc-shaped, the bottom of the threaded post extends into the interior of the sealing disc, and the outer surface of the threaded post is rotatably connected to the interior of the sealing disc.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model utilizes the rotation of the handle to drive the threaded column to rotate, and the sliding of the sealing disc in the sealing cavity to create negative pressure, which drives the slider, connecting plate and rotating plate of the positioning component to move, so that the positioning block can quickly clamp or disengage from the positioning ring, realizing convenient connection and disassembly between the furnace cover and the main body of the smelting furnace. Compared with traditional bolts, clamps and other connection methods, there is no need to tighten each bolt or adjust repeatedly. It can be operated by a single person, and the time for a single disassembly and assembly is greatly shortened. It effectively solves the problem of production process interruption caused by frequent feeding, slag removal or maintenance, and significantly improves the production efficiency of metal refining in circuit board recycling.

[0013] 2. In this utility model, the sealing rope embedded in the retaining ring fits tightly with the positioning ring, and the sealing ring outside the sealing disc and the sealing ring outside the sealing plate, along with other multiple sealing structures, ensure the sealing performance at the connection between the furnace cover and the main body of the smelting furnace. During the high-temperature smelting process, it can effectively block heat dissipation, reduce heat loss, maintain a high-temperature environment inside the furnace, and help the metal particles to melt fully. At the same time, it prevents the leakage of metal vapor or harmful gases, thus ensuring the effect of metal purification and refining, and improving the safety and environmental protection of the equipment.

[0019] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0020] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0021] A metal material purification and refining device for circuit board recycling includes a smelting furnace body 1 and a furnace cover 2 set on top of the smelting furnace body 1. The furnace cover 2 is a heat-insulating cover made of silicon carbide ceramic. A positioning ring 3 is fixedly connected to the top of the smelting furnace body 1. A retaining ring 4 is opened at the bottom of the furnace cover 2. A sealing rope 5 made of aramid fiber is embedded inside the retaining ring 4. Positioning components 6 are installed at equal intervals inside the furnace cover 2. A sealing cylinder 7 is fixedly connected inside the furnace cover 2. A sealing cavity 8 is opened inside the sealing cylinder 7. A sealing disc 9 is longitudinally and slidably connected inside the sealing cavity 8. A turntable 10 is rotatably connected inside the sealing disc 9. A threaded column 11 is fixedly connected to the top of the turntable 10. A connecting pipe 12 is fixedly connected inside the furnace cover 2. The bottom end of the sealing cavity 8 is connected to the input end of the positioning component 6 through the connecting pipe 12.

[0022] In this embodiment, the positioning ring 3 and the retaining ring 4 cooperate to initially position the furnace cover 2 and the smelting furnace body 1. The sealing rope 5 can enhance the sealing of the connection and reduce heat loss and leakage of harmful gases. The positioning component 6 can achieve rapid clamping or disengagement of the furnace cover 2 and the smelting furnace body 1 through negative pressure drive. The driving structure composed of the sealing cylinder 7, sealing cavity 8, sealing disc 9, turntable 10 and threaded column 11 can drive the threaded column 11 to rotate by turning the handle 13. The negative pressure is generated by the sliding of the sealing disc 9, thereby driving the positioning component 6 to move, realizing convenient operation by a single person and shortening the disassembly and assembly time.

[0023] Specifically, the positioning component 6 includes rotating grooves 61 equidistantly formed inside the furnace cover 2. A rotating block 62 is rotatably connected to the inside of the rotating grooves 61 via a pin. A rotating plate 63 is fixedly connected to the surface of the rotating block 62. A positioning block 64 is fixedly connected to the surface of the rotating plate 63. The inside of the rotating grooves 61 is connected to the inside of the retaining ring 4. A connecting plate 65 is rotatably connected to the surface of the rotating plate 63. A slider 66 is laterally slidably connected inside the furnace cover 2. The end of the connecting plate 65 away from the rotating plate 63 is rotatably connected to the surface of the slider 66. A fixing rod 67 is fixedly connected to the center of the surface of the slider 66. A sealing plate 68 is fixedly connected to the end face of the fixing rod 67. A sealing groove 69 is formed inside the furnace cover 2. The outer surface of the sealing plate 68 is slidably connected to the inside of the sealing groove 69. The inside of the sealing groove 69 is connected to the bottom of the sealing cavity 8 via a connecting pipe 12.

[0024] In this embodiment, the rotating groove 61 provides rotation space for the rotating block 62 and the rotating plate 63. The connection between the rotating block 62 and the rotating plate 63 can drive the positioning block 64 to rotate. The positioning block 64 can clamp the positioning ring 3 to fix the furnace cover 2 to the furnace body 1. The connecting plate 65 connects the rotating plate 63 and the slider 66, which can convert the lateral sliding of the slider 66 into the rotation of the rotating plate 63. The sliding of the slider 66, the fixing rod 67 and the sealing plate 68 in the sealing groove 69 can be driven by the negative pressure of the sealing cavity 8, thereby controlling the movement of the positioning block 64, so that the positioning block 64 can quickly clamp or disengage from the positioning ring 3 without tightening the bolts one by one or repeatedly adjusting the clamps, thus improving the disassembly and assembly efficiency.

[0025] Specifically, the top of the threaded column 11 is fixedly connected to a handle 13, and the top of the sealing cylinder 7 is provided with vent holes at equal intervals. The top of the interior of the sealing cavity 8 is connected to the exterior of the sealing cylinder 7 through the vent holes.

[0026] In this embodiment, the handle 13 makes it easier for the operator to rotate the threaded column 11, making the operation less strenuous. The vent hole allows the top of the sealing cavity 8 to communicate with the outside. When the sealing disc 9 slides upward, the gas at the top of the sealing cavity 8 can be discharged through the vent hole, avoiding the formation of air pressure that hinders the sliding of the sealing disc 9 and ensuring the smooth operation of the negative pressure drive positioning component 6.

[0027] Specifically, the outer surface of the threaded column 11 is threaded into the inside of the sealing cylinder 7, and a sealing ring is fixedly installed on the outer surface of the sealing disc 9.

[0028] In this embodiment, the threaded connection between the threaded post 11 and the sealing cylinder 7 allows the threaded post 11 to rotate and drive the sealing disc 9 to slide longitudinally along the sealing cavity 8, thereby changing the air pressure at the bottom of the sealing cavity 8. The sealing ring on the outer surface of the sealing disc 9 can enhance the sealing performance between the sealing disc 9 and the inner wall of the sealing cavity 8, prevent gas leakage, ensure the formation and stability of negative pressure, and enable the positioning component 6 to operate reliably.

[0029] Specifically, the size of the positioning ring 3 matches the size of the retaining ring 4, a sealing ring is fixedly installed on the outer surface of the sealing plate 68, and the rotating plate 63 is rotatably connected to the inside of the rotating groove 61 through the rotating block 62.

[0030] In this embodiment, the matching size of the positioning ring 3 and the retaining ring 4 ensures accurate positioning of the furnace cover 2 when placed on top of the smelting furnace body 1, facilitating the subsequent clamping of the positioning block 64. The sealing ring on the outer surface of the sealing plate 68 enhances the sealing performance between the sealing plate 68 and the inner wall of the sealing groove 69, preventing gas leakage in the sealing groove 69 and ensuring the effectiveness of the negative pressure driving positioning component 6. The rotating plate 63 rotates in the rotating groove 61 through the rotating block 62, which enables the rotating plate 63 to drive the positioning block 64 to rotate stably, ensuring that the positioning block 64 can accurately clamp or disengage from the positioning ring 3.

[0031] Specifically, the surface of the positioning block 64 is arc-shaped, the bottom of the threaded post 11 extends into the interior of the sealing disc 9, and the outer surface of the threaded post 11 is rotatably connected to the interior of the sealing disc 9.

[0032] In this embodiment, the arc-shaped design of the positioning block 64 surface allows it to fit more closely and securely when in contact with the positioning ring 3, while reducing friction between the positioning block 64 and the positioning ring 3, making it easier for the positioning block 64 to engage or disengage from the positioning ring 3; the bottom of the threaded column 11 extends into the interior of the sealing disc 9 and is rotatably connected to the sealing disc 9, allowing the sealing disc 9 to slide longitudinally when the threaded column 11 rotates, while the sealing disc 9 does not rotate with the threaded column 11, ensuring smooth sliding of the sealing disc 9 within the sealing cavity 8, thereby stably forming the negative pressure drive positioning assembly 6.

[0033] The working principle and usage process of this utility model are as follows: When in use, after the material is placed into the crucible inside the furnace body 1, the furnace cover 2 is placed on top of the furnace body 1. At this time, the positioning ring 3 is located inside the retaining ring 4, and the top of the positioning ring 3 abuts against the bottom of the sealing rope 5. Then, by rotating the handle 13 clockwise, the handle 13 drives the threaded column 11 and the turntable 10 to rotate, and the turntable 10 drives the sealing plate 9 to slide upward. At this time, the bottom of the sealing cavity 8 is in a negative pressure state, and the sealing groove 69 is also in a negative pressure state through the connecting pipe 12. The sealing plate 68 drives the slider 66 to slide away from the rotating plate 63 through the fixing rod 67. The slider 66 drives the rotating plate 63 to rotate through the connecting plate 65, so that the positioning block 64 extends into the retaining ring 4 and the surface of the positioning block 64 abuts against the bottom of the positioning ring 3, fixing the positioning ring 3 inside the retaining ring 4, thereby realizing the quick connection between the furnace body 1 and the furnace cover 2.

[0034] When it is necessary to remove the furnace cover 2, simply rotate the handle 13 in the opposite direction to disengage all the positioning blocks 64 from the surface of the positioning ring 3 and store them inside the rotating groove 61. Then, simply lift the furnace cover 2 off using the handle 13.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
